One of the most significant advantages of investing in a CNC plasma cutting system is automatic torch height control (ATHC). Automatic torch height control is important because it helps ensure that, for every project and specific cut, the torch is at the optimal height for that project, material, material thickness, and type of cut. Traditionally, with handheld plasma cutting the fabricator would need to hold the torch throughout the cut at the ideal height. This poses many potential problems because humans are not infallible. It is also very time consuming for the operator and their focus has to be 100% on that project throughout the entirety of the process rather than being freed up for other productive operations. If the fabricator’s hands move up and down, flinch or do anything else, it could diminish the cut quality or complete ruin a cut. With automatic torch height control, the software and machinery hold the torch at the ideal cut throughout the entire process, moving up and down as needed. The component of automatic torch height control that allows for that steady and accurate upward and downward movement is the torch lifter.
The torch lifter is comprised of three main parts, the motorized lifter, torch holder, and torch holder hardware. The CNC CAD/CAM software communicates with the automatic torch height control and torch lifter so that it knows when and how to move. Torch lifters allows the cutting process to be far more stabile, consistent, and fast. Because of this, production time is greatly improved with the assistance of a high quality torch lifter – both because it moves more quickly than handheld cutting and because wasted time from errors is reduced.
This is exactly why we at EZCutCNC constantly discuss the importance of investing in a high quality CNC plasma cutting system that is complete with all components that you need including state-of-the-art software that can communicate with your automatic torch height control and torch lifter. This type of investment improves fabrication shop production time significantly and reduces unnecessary waste and scrap. Additionally, because the operator does not need to hold the torch the entire time, desperately trying to maintain the accurate height, it frees their time up for other productive activities. All of these things ultimately increase a fabrication shop’s profitability.
